CPU Deprecation Warning

Daniel_H — Thu, 30 Nov 2023 17:05:14 GMT

Hi,

Since MKL 2024.0 I got this nasty warning when using applications compiled and linked with ICX 2024 on Linux:

Intel MKL WARNING: Support of Intel(R) Advanced Vector Extensions (Intel(R) AVX) enabled only processors has been deprecated. Intel oneAPI Math Kernel Library will use Intel(R) Streaming SIMD Extensions 4.2 (Intel(R) SSE4.2) instructions instead.

I'm a bit stumbled by this error/warning since the requirements are:

CPU Processor Requirements

Intel® Core™ Processor Family

...

and I've got a Intel(R) Core(TM) i7-3770 CPU @ 3.40GHz, which looks like a Core Processor to me.

So why this message ?
Is there any way to remove this warning which clutters some further output capturing processes ?

Thanks a lot for any help,

After digging a lot, I found a workaround:

export MKL_ENABLE_INSTRUCTIONS=SSE4_2

This forcedly set the instruction set to SSS 4.2 and silences the warning and let the piped instructions proceed. Fair enough...

Nevertheless I would have rather have preferred that the warning went to the stderr and not the stdout... after all that's what stderr is meant for.

Hi,

Thanks for posting in Intel Communities.

As the warning is related to the dependency on the instruction set being used by the processor and not a code error which is related to MKL, it was being printed on stdout. Kindly let us know if you need any other assistance.

Thanks & Regards,

Aryan.

OK, thanks for the answer.

I'll live with that until I got the money to upgrade to a new CPU...
